Multi-agent communication for AI coding tools. Agents message, watch, and spawn each other across terminals. Use when setting up hcom or troubleshooting.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# hcom — multi-agent communication for AI coding tools AI agents running in separate terminals are isolated. hcom connects them via hooks and a shared database so they can message, watch, and spawn each other in real-time. Start an agent with `hcom` in front, then prompt normally. Use hcom to: - coordinate multi-agent pipelines - run different AI CLIs as each other's subagents - avoid copy-pasting ```bash uv tool install hcom hcom claude # or: hcom gemini, hcom codex, hcom opencode, hcom kilo, hcom pi, hcom omp, hcom agy, hcom cursor, hcom kimi, hcom copilot, hcom qoder, hcom grok, hcom hermes hcom # TUI dashboard ``` Quickstart: ```bash # terminal 1 hcom claude # terminal 2 hcom codex ``` Prompt normally — e.g. `review what claude did and send it fixes` --- ## what humans can do tell any agent: > send a message to claude > when codex goes idle send it the next task > watch gemini's file edits, review each and send feedback if any bugs > fork yourself to investigate the bug and report back > find which agent worked on terminal_id code, resume them and ask why it sucks --- ## what agents can do …

How to install
mdr add aannoo/hcom/hcom-agent-messaging@sha256:dc2f775b0d62a68bThe line at the top of this page pins the label git:20261015.471f442, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
